Since Telltale Games delisted all their games from digital platforms like Steam, I decided to preserve this game by taking an increasingly rare physical copy, making a clean rip, getting high-quality scans of the cover and disc, and uploading it here.
It's an old Windows XP game protected by SecuROM, however an open-source tool called SecuROMLoader is able to bypass this. Go to the link below, download the latest release, put the version.dll file next to the game's actual executable (Bone1v20.exe). I've included a version.json in this Internet Archive as well. Put that file next to the executable as well. This will allow you to launch the game on modern versions of Windows, likely even Windows 11.

This fix is far better than the old iphlpapi.dll file that was floating around the internet, as it's flagged as a virus pretty much everywhere, and it stopped working after an early Windows 10 update. This new solution also works for Bone: The Great Cow Race, which you can find elsewhere on the internet if you look hard enough.
Have fun!
